National Geographic enjoyed having the guys from RiffTrax take over their cable TV airwaves on April Fool’s Day that they’ve invited Michael J. Nelson, Kevin Murphy and Bill Corbett back for two more RiffTrax Total Riff Off specials to air in primetime this December.

RiffTrax told The Comic’s Comic the good news today.

Before they were RiffTrax, of course, Nelson, Murphy and Corbett were known to TV viewers as the farewell cast of MST3K.

You can get a flair for the flavor of what they’ll do for National Geographic Channel by checking out their three April Fool’s commentaries, or check them out as they riff live onstage and simulcast to more than 700 movie theaters nationwide before their take on Anaconda on Oct. 30, 2014. And in December, they’ll be screening and riffing over the footage from a horrible 1959 film called Santa Claus. “Just in time for Christmas, all your favorite characters are here: Santa, his reindeer, Merlin, the Devil himself and all his fellow devils, and of course, a giant shirtless blacksmith,” Nelson said. “Merry Christmas?!”

But wait, you say, how can we think about Christmas when it’s not even Halloween yet?

Alrighty then. Rifftrax offers some fresh takes on a Halloween classic, “It’s The Great Pumpkin, Charlie Brown!” Roll the clip (thanks, Mashable)!
